Fox’s decision to cancel “Brooklyn Nine-Nine” has left the show’s fans despondent, but Lin-Manuel Miranda is ready for a fight.

The “Hamilton” mastermind, a vocal fan, called on his Twitter followers on Thursday to launch a social media campaign to save the show. “Renew Brooklyn Nine Nine. I only watch like 4 things. This is one of the things,” he wrote, adding the hashtag #RenewB99.

In a subsequent tweet, Miranda tagged the Fox Twitter handle, calling on them to reverse the decision.

“Brooklyn Nine-Nine” fell victim to Fox’s house-cleaning on Thursday afternoon, getting the axe along with fellow comedies “The Mick” and “Last Man on Earth.” The show was averaging 2.7 million total viewers in its fifth season, including week-delayed viewing, and was deemed too low to eke by with Fox losing a chunk of programming time to an additional night of football in the fall.

All three shows were well known to be on the bubble, being tied for 13th out of 20 scripted Fox shows. But “Brooklyn Nine-Nine” is a critical darling and “The Mick” was new enough to see plenty of room for growth.

The season finale, which will also serve as the series finale (at least, for now), will air May 20.
